Along with the World Series ring, Sheen is selling the contract, signed by Ruth, which brought him to the New York Yankees from the Boston Red Sox in 1919 and sparked the notorious "Curse of the Bambino."

The contract could fetch another $750,000.

“This is the best of the best of the best. It's the greatest player ever, the greatest season ever from the greatest team ever,” the auctioneer said.

The auction, run by LeLands, ends Friday, June 30. For more information, click here.
